MySQL监控工具之innotop

innotop是一个通过文本模式显示MySQL和InnoDB存储引擎的监测工具。innotop是用perl语言开发，这是它能更加灵活的使用在各种操作平台之上，它能详细的的监控出当前mysql和innodb存储引擎运行的状态，以便维护人员根据结果合理的优化数据库，让数据库更稳定更高效的运行，innotop依赖于系统的perl-ExtUtils-MakeMaker软件包。1.安装perl依赖包[root@linuxidc ~]# yum install perl-ExtUtils-MakeMaker
[root@linuxidc ~]# rpm -aq | grep perl-ExtUtils-MakeMaker
perl-ExtUtils-MakeMaker-6.55-136.el6_6.1.x86_64
[root@linuxidc ~]#2.下载安装innotop监控工具
[root@linuxidc ~]# wget http://innotop.googlecode.com/files/innotop-1.9.0.tar.gz
[root@linuxidc ~]# tar xvf innotop-1.9.0.tar.gz -C /usr/local/
[root@linuxidc ~]# cd /usr/local/innotop-1.9.0/
[root@linuxidc innotop-1.9.0]# perl Makefile.PL

3.innotop使用帮助和监控实例
[root@linuxidc innotop-1.9.0]# ./innotop --help
Usage: innotop <options> <innodb-status-file> --[no]color -C Use terminal coloring （default）
--config -c Config file to read
--count Number of updates before exiting
--delay -d Delay between updates in seconds
--help Show this help message
--host -h Connect to host
--[no]inc -i Measure incremental differences
--mode -m Operating mode to start in
--nonint -n Non-interactive, output tab-separated fields
--password -p Password to use for connection
--port -P Port number to use for connection
--skipcentral -s Skip reading the central configuration file
--socket -S MySQL socket to use for connection
--spark Length of status sparkline （default 10）
--timestamp -t Print timestamp in -n mode （1: per iter; 2: per line）
--user -u User for login if not current user
--version Output version information and exit
--write -w Write running configuration into home directory if no config files were loadedinnotop is a MySQL and InnoDB transaction/status monitor, like "top" for
MySQL. It displays queries, InnoDB transactions, lock waits, deadlocks,
foreign key errors, open tables, replication status, buffer information,
row operations, logs, I/O operations, load graph, and more. You can
monitor many servers at once with innotop.[root@linuxidc innotop-1.9.0]# ./innotop -u root -psystem -h localhost -S /tmp/mysql.sock
